A Hills Hoist is a height-adjustable rotary clothes line, manufactured in Adelaide, South Australia by Lance Hill since 1945. The Hills Hoist and similar rotary clothes hoists remain a common fixture in many backyards in Australia and New Zealand. They are considered one of Australia's most recognisable icons, and are used frequently by artists as a metaphor for Australian suburbia in the 1950s and 1960s.[1] Although originally a product name, the term "Hills Hoist" became synonymous with rotary clothes hoists in general, throughout Australia.

As early as 1895 Colin Stewart and Allan Harley of Sun Foundry in Adelaide applied for a patent for an 'Improved Rotary and Tilting Clothes Drying Rack'. In their design the upper clothes line frame tilted to allow access to the hanging lines.[2]Gilbert Toyne of Geelong patented four rotary clothes hoists designs between 1911 and 1946. Toyne's first patented clothes hoist was sold though the Aeroplane Clothes Hoist Company established in 1911.[3] It was Toyne's 1925 all-metal model (Australian Patent No. 24553/25) with its enclosed crown wheel-and-pinion winding mechanism that defined clothes hoist designs for decades to follow.[4][5]

Lance Hill began to manufacture the Hills rotary clothes hoist in his backyard in 1945. His wife apparently wanted an inexpensive replacement to the line and prop she had for drying clothes.[6][7]

Lance Hill's brother-in-law Harold Ling returned from the war and joined him to form a partnership in 1946. Ling became the key figure in expanding the production and marketing of the Hills Hoists. In 1947 Hills Hoists began manufacturing a wind-up clothes hoist which was identical to Gilbert Toyne's expired 1925 patent with the crown wheel-and-pinion winding mechanism.[8][9] Initially the clothes hoists were constructed and sold from Lance Hill's home on Bevington Road, Glenunga.[10] Soon production moved to a nearby site on Glen Osmond Road and within a decade the factory had relocated to a larger site at Edwardstown.[8] The company Hills Hoists became Hills Industries in 1958.

A Darwin family reported that the only thing left standing after Cyclone Tracy was their Hills Hoist.[11] The company is still Australian owned to this day, trading as Hills Holdings, and sells other products including TV antennae and playground apparatus. The Hills Hoist is listed as a National Treasure by the National Library of Australia.[12]
